摘要：

'Adaptive' or 'stationary-phase' mutation is a collection of stress responses promoting mutations, some of which are advantageous. In 2000 and 2001, in Escherichia coli, adaptive gene amplification was documented, and a parallel adaptive point-mutation mechanism was linked to the error-prone DNA polymerase, DinB (pol IV). We suggest that DinB homologues may contribute to adaptive strategies of pathogens, including antigenic variation.
